I don't know...  I like naming major releases according to visible
changes for users, so I think that 2.60 would have deserved the 3.0
naming much more than current autoconf.git, for example because of the
introduction of datarootdir.  One by one the changes in implementation
in the last month were incremental (which is very good), and likely not
visible from even the most intricate outside uses (such as gnulib's).
Libtool is an exception, but at least I think we catered decently for it.

On the other hand, this is probably *the* release that completes the
plan began in 2.50, with so many m4sugar/m4sh APIs going public, and a
clear idea of what we expect from a "modern" shell.  And we all know
that some deprecation proposals put out in 2.50 are going to stay here
forever, so there's no reason to wait for them to go away before calling
a release 3.0.
